The Helokeep K6-Pro is a Class-2 fat tire electric bike with a 750W brushless motor (1,500W peak) and a 48V 17.5Ah removable battery. It runs 20 x 4.0 inch snow-tread fat tires on a high-carbon steel frame with front and rear suspension, dual disc brakes and five riding modes. Throttle speed is capped at 20 MPH, with up to 30 miles on throttle alone or up to 50 miles with pedal assist. It suits heavier riders and rough terrain, but its steel frame and fat tires make it a heavy, bulky machine next to lighter alloy commuter e-bikes.
